I have an intermitant brake problem with my 1993 245. Best guess is that it is ABS related but never has been fixed. The master cylinder, wheel cylinders, abs sensors ahve been replaced and the system disassembled and cleaned repeatedly. After the disassembly/cleaning the problem will disappear for 1 week to 1 month and then reappear.
Symptoms: When easing up to a light, lightly pressing the brake pedal, the pedal will drop and then come back up. It feel light part of the system connected to the pedal is rolling over a bump. At the same time, there will be a grinding noise from the front of the car in the wheel area. The wheel will also pull to one side at the same time. The pedal feels like it is connected to something rough.
At one point, the ABS light would come on. When the light was on, the problem would not occur. The light no longer comes on but the intermittant problem continues.
Several mechanics have tried to fix(including the local dealership), but the old brick is shy and has only displayed the problem in a mechanic's presence once.
Any thoughts? If not any referral to a good Old Volvo mechanics in the South Pinellas County, Florida Area? Thanks for your help.
